Light: Reflection and Refraction

Lesson Plan

State Standards:

prism refraction

Physical Sciences, Grades 3-5: Standard 12 – Recognize that light travels in a straight line until it strikes an object or travels from one medium to another, and that light can be reflected, refracted, and absorbed.

Essential Question:

How does the way light reacts impact what I see in the world around me?

Lesson Question:

Introduction:

Have you ever wondered why you can see your reflection in a mirror? Or why your straw appears “bent” as it enters your glass of water? Well, if you have, you are going to find the answers your looking for! In this investigation, you will learn all about light and how it behaves.

Task:

To investigate the behavior of light as it interacts with objects in the world around you.

6. Knowledge Expression Activity: Prezi

Using the knowledge derived in this series of activities, create a Prezi that illustrates/explains how light behaves.

Conclusion:

Through these interactive investigations, we have gained an understanding of how light behaves, including basic ideas about reflection and refraction.

Assessments:

Students will be assessed on Wiki posts, as well as on the final Prezi presentation.
